To all whom it may. concern j Be it known that 'I, LOUIS BINDER, a citizen of the United States, and a resident of Newark, county of Essegand' Stateof New Jersey, have invented certain new and useful Improvements in Blanks for and Methods of Forming Box Bodies, of which the following is a specification. I This invention relates to animproved box, and is particularly adapted'for the manu- 'facture ofcigar boxes of heavy cardboard which is not ieasily- -broke'n on a-line of SCOT,

ing, the invention being-particularly directed blanklfrom which the box is the end walls shown slightly separated there from. Figure 2-is theblank shown in Figure 1 ,but on a slightly reducedscaleand turned over readyfor folding, with the strengthening sheets on the front wall and the, end walls of the box in position. Figure 3 is a detail*perspejct;ivef view of the juncture of the bottom and one of the wings of the 7 'blank. Figure 4 is a similar view with the parts bent or folded at right angles. Figure 5 is a view similar to Figure 4, with the bottom pushed in and the bottomosheet in position, Figure 6-is a perspective view of the bottom sheet, and Figure 7 is a perspective view of a completed corner of the box.

The box, which is adapted to be made from the blank described and shown herein, is of heavy material, and. in the drawing I show a blank comprising a bottom 10, wings 11 and 12 to form the front and back, respec-' tively, of the box, and 13 and 14 to form the end walls of the box when they are folded upward from the bottom 10.

In preparing the blank, and usually while cutting it out, it is also provided with cuts 15 whichare arranged at where the juncture of the bottom and of the wings, which will form the walls, is placed. Such cut is shown more in detail in Figure 3, and it will be noticed that it extends more than half way through the material; in fact it usually 6X1- tends about three quarters of the way through the material so as to define the place of folding, making the folding comparative 1y easy, and providing the abutting pon' tionsfafterthey'are folded, with sharp cor ners, which, it will be understood, materially enhances thefappearance of the box.'-

' The cuts 15 are preferably made all at one time means o-fa set ofjblades, and the cuts at'a, which arethecuts that arepl-acedat the juncture of the end walls 13 and 141 and the bottom 10,"are inset from-the ends of' the' wings 11' and 12 so that when the wings are.- folded upthe walls 11 and 12 will engage" the side" edges of the wings 13 In cutting theseiboxes it is usual to dispose'the materialthat is being cut so that the grainof the fibre, which is shown by surface shading in Figure 1, is longitudinal of the bottom andof'the'wa'lls 11 and 12, but this dispositionmakes it transverse to the wings 13 and 14:. Thematerialis substantially stiff when it is bent across the grain, but is'brittle andeasilybreaks when broken with the grain.

. To overcome the weaknessin the walls 13 and 141:,sheets'1'6p which can be of thinner material but arejusually of cardboard, are

fastened, usually-by" pasting therm on what will be the outer facesoffthe'end'walls 13 and 14, and they are usually made long, enough so that they project beyond and'will enga e :v p

the ends of the wings 11 and 12 when they are folded upto form the front andvback walls of the box. The sheet, after beingso strengthened, is turned over, as shownin Figure 2, and is then folded up so that the wings are vertical, the folding, of course, taking place at the weakened portion in line with the cuts 15, the folded portion being shown in :Figure 1, so that sharp corners 17 and 18 are provided, and after the end walls are folded so as to beperp'en dicular to the bottom 10, the 'bottomis pushed in, as shown in Figure 5, from the position shown in Figure 4, the weakened portion forming a small web that engages the parts even after the bottom 10 is pushed inward, and since the bottom 10 has anora ma-l tendency to again move outward from s between the folded-wings, I place a strength ening sheet 19 which is of substantially the same size as the bottom of the box and which 'is'securely pasted to the bottom, as shown in Figures 5 and. 7.

The usual corner bindings used on boxes of this kind have been omitted from the drawing as they are no part of the invention, but it will be understood that they are used as the trade now uses them in holding the parts in their relative positions. v

When cigars are placed in boxes: they are pressedatter they are placed in the box, and the pressure is particularly strong against the end walls l and lehsince the lmlgi'ng of the contents is in that direction as the ciga-rs arelaid transversely in the box. v "his o utward. pressure does not distort the present box because the sheets 16, with the fibre of each sheet at an angle to the fibre of the all to which it is attached, prevents the buckling or splitting nsual in heavy card board boxesnsed as cigar boxes which. have been heretofore employed I The cutting and the folding as shown in Figures 5 and '7,,piovides sharp corners on all the corners ofthe box, which not only provides a better appearance, but nlitliQS ltpossible to more securely paste the parts togethen and, as will be seen tromliigure 7, the abutment of the sheet 16; Where it probeyondfihe end Wall, fitted snugly av net the ends of the front and rear walls so that any inward movement of the Walls is thus resisted. a r i 7 111, cases of header boxes I may: place a strengtheningsheet '20, on Whatwill be the outer face of, say, the front Wall.

I claim V A box bodyi'orined of a. blank of heavy cardboard. having acentral body )ortion, and Wings, to form end andside Walls the abutting 1) arts of said, portions being defined by cuts extending nearly through the n aterial, and sheets of material secured to the outer faces otthe end Walls and adapted to abut on'the ends of the side Walls, the grain of the fibre in a sheet being at an angle to the grain of the Wall.

2. A box body :t'o'rnied of a blank of heavy cardboard having a central body portion, and Wings to 01m end and side Walls, the abutting parts of said portions being de fined by cuts extending nearly through the material, and a sheet of ina'terial fastened to each end Wall and arranged so that the grain of, its fibre is at an angle to the grain of the The niethjo d'of forming boxes of heavy cardboard"consisting in the provision of a blank to for-in the bottom and the sides of the box, cutting into said material niore than half 'v ay through aifixing sheets to the end falls 'oithe box on the outside thereof and projecting therefrom so that when lioldedthje sheets will engage the ends of the I wallsfaifid then folding-the Walls "up from the bottom at the cut' 'portions.

in t inion'y that relish the foregoih I ere'to. set-in hand, this 28th day of December; 1921.
